Care of Your Opener
LIMIT AND FORCE ADJUSTMENTS
Weather conditions may cause some
minor changes in door operation
requiring some readjustments,
particularly during the first year of
operation.
Pages 29 and 30 refer to the limit and
force adjustments. Only a screwdriver is
required. Follow the instructions carefully.
Repeat the safety reverse test (page 31)
after any adjustment of limits or force.
MAINTENANCE SCHEDULE
Once a Month
• Manually operate door. If it is unbalanced or binding, call a
trained door systems technician.
• Check to be sure door opens & closes fully. Adjust limits and/or
force if necessary. (See pages 29 and 30.)
• Repeat the safety reverse test. Make any necessary
adjustments. (See page 31.)
Twice a Year
• Check chain tension. Disconnect trolley first. Adjust if
necessary. (See page 15.)
Once a Year
• Oil door rollers, bearings and hinges. The opener does not
require additional lubrication. Do not grease the door tracks.
THE REMOTE CONTROL BATTERY
The Lithium battery should produce power for up to 3 years. To
replace battery, use the visor clip or screwdriver blade to pry
open the case as shown. Insert battery positive side up (+).
Dispose of old battery properly.

Having a Problem?
1. The opener doesn't operate from either the Door Control or
the remote control:
• Does the opener have electric power? Plug a lamp into the
outlet. If it doesn't light, check the fuse box or the circuit
breaker. (Some outlets are controlled by a wall switch.)
• Have you disabled all door locks? Review installation
instruction warnings on page 15.
• Is there a build-up of ice or snow under the door? The door
may be frozen to the ground. Remove any restriction.
• The garage door spring may be broken. Have it replaced.
• Repeated operation may have tripped the overload protector in
the motor. Wait 15 minutes and try again.
2. Opener operates from the remote, but not from the
Door Control:
• Is the door control lit? If not, reverse the wires. If the opener
runs, check for a faulty wire connection at the door control, a
short under the staples, or a broken wire.
• Are the wiring connections correct? Review
Installation Step 6.
3. The door operates from the Door Control, but not from the
remote control:
• Is the door push bar flashing? If your model has the Lock
feature, make sure it is off.
• Program the opener to match the remote control code. (Refer
to instructions on the motor unit panel.) Repeat with all
remotes.
4. The remote control has short range:
• Change the location of the remote control in your car.
• Check to be sure the antenna on the side or back panel of
motor unit extends fully downward.
• Some installations may have shorter range due to a metal door,
foil backed insulation, or metal garage siding.
5. Opener noise is disturbing in living quarters of home:
• If operational noise is a problem because of proximity of the
opener to the living quarters, the Vibration Isolator Kit 89LM
can be installed. This kit was designed to minimize vibration to
the house and is easy to install.
6. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are off.
• Remove the bell wire from the door control terminals and
operate from the remote only. If this solves the problem, the
door control is faulty (replace), or there is an intermittent short
on the wire between the door control and the motor unit.
• Clear memory and re-program all remote controls.
